# 1.简介
2023-01-10 14:43:48 +08:00
PikaPython 是一个完全重写的超轻量级 python 引擎,零依赖,零配置,可以在 **Flash ≤ 64KB, RAM≤ 4KB** 的平台下运行(如 stm32g030c8 和 stm32f103c8),极易部署和扩展,具有大量的中文文档和视频资料。
2022-07-02 20:13:13 +08:00
2023-01-10 14:40:33 +08:00
PikaPython 也称 PikaScript、PikaPy。
2022-07-02 20:13:13 +08:00

2023-01-07 16:16:28 +08:00
PikaPython 具有框架式 C 模块开发工具,只要用 Python 写好调用 API ,就能够自动连接到 C 模块,非常方便快捷。不用手动处理任何全局表、宏定义、等等。
2022-07-02 20:13:13 +08:00
所有的工具也是全部开源的,在 tools 目录下。

2023-01-07 16:16:28 +08:00
PikaPython 也支持 MDK、iar、RT-studio 等常见 ide 开发,能够轻松地调试 C 模块。

这几个 Demo 占用的 RAM 最大值只有3.56K, 把1K的堆栈也算上就是4.56K, Flash 最大占用是30.4K,以 STM32F103C8T6 的 20K RAM 和 64K Flash 为标准, RAM 才用掉不到25%, Flash 才用掉不到50%。

我们可以简单对比一下 micropython 的常用芯片 STM32F405RG 和这次跑 pikapython 的芯片STM32G070CB

## 拓展能力如何呢?

除了设备驱动之外,为 mcu 开发自定义的 python 脚本绑定在 pikapython 的开发框架下非常轻松,下面两个 Demo 就是自定义的C模块拓展, 这个 Demo 基于 ARM-2D 图像驱动库开发了一些 python 脚本接口。
